IMPROVEMENT IN GANG-PLOWS.

To all whom it may concern:

Be it known that I, OAROLL ATWOOD, of Lebanon, in the county of St.Clair and State of Illinois, have invented a new and Improved Gang-Plow;and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specification, in which Figure l is. a sidesectional view of my invention, taken in the line m at, Fig. 2; Fig. 2,a plan or top View of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and improved gang-plow and it consistsin a novel construction and arrangement of parts, whereby the plows maybe very readily adjusted to gage the depth of the furrows, as may bedesired, the plows adjusted laterally according to the width of furrowrequired, and the plows prevented from choking with weeds, grass, &c.

A represents an axle, and B B wheels attached thereto, one wheelB,having its arm rather higher than the other, in order that said wheelmay run on the land side or unplowed portion of the field, and, inconsequence of being higher than the other wheel, B, which runs in thefurrow, admit of the framing of the machine being level or horizontal.

G O are two parallel bars or sills, the rear parts of which are boltedpermanently to the axle at right angles thereto, and the front endsconnected by a transverse bar, D, to which the draft-pole E is attached.

F F are also two parallel bars or sills, which are attached to the axleA and bar D, but not permanently, the bolts a, which pass through them,passing through an oblong slot, 1), in the axle A and bar D, to admit ofthe sills F F being adjusted at a greater or less distance apart, forthe purpose hereinafter set forth.

G G are two plow-beams, the front ends of which are attached to thesills F F by joints or hinges c c, which admit of the plow-beams beingraised or lowered from c c as centers. These plow-beams pass throughmetal guides or straps A, which are secured to the rear ends of thesills F F, andare connected at their upper ends by a metal bar, H, oneend of which has a longitudinal slot, d, made in it for the bolt d topass through and admit of the lateral adjustment of the beams with thesills F F. The beams G" G are also con nected near their rear ends bytwo metal bars.

I I, one above and the other below the plowbeams, said bars beingconnected permanently at one end to one of the beams, and the oppositeends passing between a clamp, J, and the beam, the clamp admitting ofthe bars I moving when the beams G are to be adjusted.

K K are the plows, which may be of the usual form employed for turning afurrowslice. These plows are attached to metal standards L L, the upperends of which are secured to the rear of the beams G G by pivotbolts 6.(See Fig. 1.)

To the rear part of each laudside f of the plows a rod, M, is connectedby a pivot, g, and the upper parts of these rods have screwthreads cuton them to receive jam-nuts h h, the rods passing through plates N atthe rear of the beams, with a nut, h, above and one below them. (SeeFig. 1.)

By tur'ning or adjusting the nuts h 71, the points of the plows K may beraised and lowered to suit or gage the depth of the furrow required, andthe plows are elevated entirely above the surface of the ground, whennecessary, by means of a lever, O, which is connected by a strap, P,with the beams, and has its fulcrum on the bar H.

The plows are retained in an elevated state by means of a catch-lever,Q.

By adjusting the sills F Flaterall y, or nearer together or fartherapart, the width of the furrow-slice may be regulated as desired.

R R represent fenders, which are composed of bars attached to the rearof the sills F F. The lower portion of these bars have a horizontalposition and an oblique one relatively with the plows, the upper partsbeing vertical and attached at their upper ends to the sills. Thesefenders serve to prevent the plows being choked up with weeds, grass,&c.

I claim as new and desire to secure by Letters Patent The metal bars Hand I I, in connection with the clamp J, all arranged substantially asshown, to admit of the lateral adjustment'or the plow-beams with thesills F F, for the purpose set forth.

OAROLL ATWOOD.
